For a really old Samsung CLP-510 printer (2001), cartridges are very few and far-between to find. Had problems with cartridges from other vendors. My purchase from InkTonerShop has worked perfectly from Day 1 - never a problem thereafter. I will definitely purchase again from this vendor. Customer service was excellent - above par in all aspects.
